I have a 20gig hard drive which is shown as such on boot up, however when I view the hard drive in MyComputer it tells me it has a capacity of only 8gigs and therefor I can only access 8gigs. How can I recover the whole drive capacity? I have tried fdisk without success. (I assume I made the correct choices).
Any suggestions will be warmly received, Darrell.

The problem is because your motherboard won't support hard disk bigger than 8GB. To enable it to support your new 20GB hard disk, go to your hard disk manufacture website and download the tools to enable your mother board to support larger hard disk.

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Comments made already may well be valid but I'm not yet clear whether your 20GB hdd ever worked correctly. Please let us know whether it is new to your system or whether it is just not working correctly now (but was OK some time in the past).

I agree with patrick, although older system motherboards do not support large volume harddrive, I'm not sure this is the case here.  You mention a 20 gb Harddrive, is it a new drive due to your old drive failing ??
How old is the system, detail system specs ???
When you installed the harddrive, what were your harddrive detection selections in the BIOS ??  Auto, manually input size, LBA etc.....  This info will allow us the capability to further clarify your situation.
Thnaks !!

Also in fDisk, review the partition information. Namely: is there more than one, and if so, what is said about others? OS may also be of import, since older ones were not made to access large space, until later revs.

You must have used fdisk on a hard drive that's larger then 64GB.  For example, if you have a 70GB hard drive, fdisk will take the 64GB limitation, subtract it from 64, giving you 8GB of hard drive partitioned space.  You can either go here, http://support.microsoft.com/default.aspx?scid=kb%3Ben-us%3B263044, or use make startup disks with partition info and partition and format there.

Hey,

To solve the problem try the following sequence of steps:

1. Look into the jumper setting at the back of the hard disk. If it is not set to either master or slave place the jumper at master position.

2. In the BIOS HDD detection, make sure the correct size is detected. Then go to standard CMOS setup and make sure you have the LBA mode set.

If the above two doesnt work

3. FDISK your drive giving Y at startup. Have a look at the current partition info. If that doesnt show the full 20 GB then partition as required and then format all the partitions.

This should solve the problem. Else make sure your board supports higher capacity disk drives.

For this i should have the configuration of your system and the BIOS version.
